This board is then placed into a cutout (hole or slot) located in the center of a bus bar. Figure 1 shows the alternate approach using two DRV425 devices. When a cutout (hole or slot) is placed in the center of the bus bar, the current is split in two equal parts. Each side of the cutout will generate magnetic field gradients that oppose one another inside the cutout. The high

6 FAQs about [Capacitors can be dropped into the empty busbar]

How do you connect a capacitor to a bus bar?

The most common and easiest connection method for a capacitor onto a bus bar is a screw or bolt on connection. Soldering or spot welding connection methods can also be used, but they greatly increase the cost and complexity of the design. In sum, the bus bar design starts along with the power electronics converter design.

Why does a bus bar have a high frequency capacitor?

The laminated structure of the bus bar creates a high frequency capacitor that helps mitigate the noise propagation , , though this unintended filter is likely not enough to completely remove the issue. An unavoidable result of fast switching devices is the high frequency harmonics, termed Electromagnetic Interfer-ence (EMI) .

What happens if a capacitor fails?

There are 6 capacitor units in series and 3 group of units. If one capacitor element fails, the element is shortened and the voltage on the remaining elements is 17 or about 2.8% increase in the voltage. The capacitor bank continues in service; however, successive failures of elements will lead to the removal of the bank. III.

How does a bus bar conductor improve DC current distribution?

As illustrated by Fig. 9, DC current distribution is improved by splitting the positive and negative terminals in three. This reduces ohmic losses and evenly spread the heat across the bus bar, which reduces the hot spots. Typically, the bus bar conductors are sized for a 30 C self-heating temperature.

How is AC current distributed on a bus bar?

The AC current on the bus bar circulates between five DC-link capacitors and three IGBT modules, as a result, the experimental verification for AC current distribution can be implemented by examining the currents in each DC-link capacitors. The current in one of the capacitors is shown in Fig. 17a, while a zoomed in view is shown in Fig. 17b.

How stray inductance and capacitance are measured in a bus bar?

In order to validate the bus bar designs and analysis, stray inductance and capacitance were measured using a precision impedance analyzer, e.g., Keysight 4294A. As previously stated, the capacitor connections must be short circuited to evaluate the bus bar stray inductance.
